How to reset the filter capacity

Note: Always reset the filter capacity when you replace the filter cartridge.

This is necessary to set the remaining filter capacity back to its initial value

(i.e. 2500, 1500 or 900 litres).

Press the reset button for 2 seconds

Press the filter capacity selection button.

The set filter capacity flashes on the display for 4 seconds.

If the new filter cartridge has the same capacity as the old

cartridge, simply wait until the setting stops flashing.

If the new filter has a different capacity, press the filter capacity

selection button again until the display shows the capacity of your

filter cartridge (1500-2500-900-1500 etc.).

Stop pressing the filter capacity selection button when the display

shows the capacity of the new filter cartridge.

The selected filter capacity and the remaining filter capacity are

shown for 5 seconds.
replacing the battery

The battery lasts approximately one year in case of normal domestic

use. Replace the battery when the à symbol lights up and flashes. This

appliance runs on 1 button-type CR2032 (3V) lithium battery, which is

generally available.

Remove the water purifier from the tap.

Wipe the entire water purifier with a dry cloth.

Place the new battery (see ‘Inserting the battery’ in chapter

‘Preparing for use’).

Reattach the water purifier to the tap (see the installation

instructions for your adapter type in chapter ‘Preparing for use’).

Note: When you replace the battery, the water purifier remembers the

remaining filter capacity. If no battery is inserted in the water purifier, the

remaining filter capacity is not counted down.
